As of April 1, 2011, Canada's population was estimated at 34,349,200, up 70,800 (+0.2%) from January 1, 2011. Alberta registered the fastest first-quarter increase (+0.4%) in the country.
Nationally, the growth in population was lower than the increase of 85,200 estimated for the first quarter of 2010. This slowdown was mainly the result of a decline in net international migration. Canada had a net inflow from international migration of 49,300 in the first quarter, down from 61,300 in the first quarter of 2010. This decline was due mainly to lower levels of immigration.
During the first quarter, Canada received 49,500 immigrants compared with 58,100 for the same quarter in 2010.
Newfoundland and Labrador's population fell by 700 (-0.1%) to 508,400 as of April 1, partly the result of a net outflow of about 500 people to interprovincial migration.
Prince Edward Island's population rose by nearly 400 (+0.2%) to 143,800. It was the only province in Atlantic Canada in which the population increased in the first quarter. The province received nearly 500 immigrants, the highest level among all the provinces relatively to its total population.
As of April 1, Nova Scotia's population was estimated at 942,300, down nearly 1,100 (-0.1%) from January 1.

This was Nova Scotia's highest net outflow to other provinces since the first quarter of 2007.
The population of New Brunswick changed little in the first quarter and was estimated at 753,000 on April 1.

As of April 1, Ontario's population was estimated at 13,310,900, up by 28,400 (+0.2%) from January 1, the slowest first-quarter growth since 1996. This was mainly a result of immigration levels. The province received 20,100 immigrants in the first quarter, its lowest first-quarter level since 1998. Meanwhile, Ontario's net outflow from interprovincial migration (-700) was the smallest first-quarter net outflow since 2003.
Manitoba's population increased by just over 2,700 (+0.2%) to 1,246,400. Manitoba had a net inflow of nearly 2,800 people from international migration, the highest for a first quarter since 1972, the first year covered by the current demographic accounting system. However, the province had a net outflow of 1,000 in its exchanges with other provinces, the largest first-quarter net outflow since 2006.
As of April 1, Saskatchewan's population was estimated at 1,054,000, an increase of just over 1,900 (+0.2%) compared with January 1. The province's increase was tempered by a net outflow (-600) from interprovincial migration. It was Saskatchewan's first net outflow in its exchange with other provinces since the third quarter of 2006.
Alberta's population reached 3,758,200, an increase of just under 15,500 (+0.4%). Alberta had a net inflow of nearly 5,300 in its exchanges with other provinces, the highest for a first quarter since 2006.

As of April 1, the population of British Columbia was estimated at 4,563,300, up just over 9,200 (+0.2%) since January 1. It was the slowest increase for a first quarter since 2005. The province had a net inflow from international migration of just over 7,000, the lowest level for a first quarter since 1998.
